ROTARY SPADING-PLOW.

Specification of Letters Patent. Patented Dec. 29, 191&.

Application filed. January 24, 1914. Serial No. 814,167.

- To all'whom it may concern Be it known that I, ELIAS H. CowAR'r, acitizen of the United States, residing at Sacramento, in the county ofSacramento and State of California, have invented certain new and usefulImprovements in Rotary Spading-Plows; and I do declare the following tobe a clear, full, and exact description of the same, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon,

which form a part of this application.

This invention, relates to improvements in plows used for tilling thesoil, the object of the invention being to produce a rotary plowespecially constructed for use in handling land covered with weeds,matted grass,

tules or other foul matter. I

The aim of the invention is to produce a spading plow which is soconstructed with blades and cutters that after the foul matter has beenpreviously matted directly in front of such blades or cutters, theywill, with the operation of the plow, engage and cut through the foulmatter prior to plowing into the dirt. Such blades or cutters will thencarry the foul matter to a predetermined ppint at the rear of the plowwhere a discharging means will then dis-. charge the same from theblades or cutters' in order that it may be cut and chopped into a finemass by other mechanism. 7

A further object of the invent-ion is to produce a simple andinexpensive device and yet one which will be exceedingly effec- .tivefor the purposes for-which it is de the parts as will fully appear by aperusal of thereof, but at one point making an abrupt 10C signed. I

These objects, I accomphsh by means of such structure and relativearrangement of the following specification and claims.

On'the drawings, similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a top plan view, partly broken out, of the completestructure. side elevation of the same. Fig. 3 is a sectional view of oneend of one of the plows taken relatively on a line Y-Y of Fig. 1. Fig. 4is a sectional view of one of the complete plows taken relatively on aline XX of Fig. 3.

Referring now more particularly to the characters of reference on thedrawings, the

numeral 1 designates the supporting frame which is suitably mounted onwheels 2 at the forward end and provided with any suit able steeringmechanism 3 and with suitable motive power consisting of steam engines,

explosive motors or any other suitable power, the kind here shown beingsteam engines l, there being-two of such engines for the purpose willpresently appear.

The supporting frame 1 is divided by a central beam or bar 5 and.journaled between each of the sides of the frame land the bar his ashaft '6 mounted on each of which is a plow comprising a pair of spaceddisks 7 having outwardly projecting annular flanges Secured to the outerperiphery of the disks 7 is a suitable inclosing plate 9 projectingbeyond the outside edges of the said disks 7 a suitable distance asshown. Secured to the outside of the plate 9 are a plurality of spacedspades or cutters 10 disposed in a slightly oblique manner with respectto the aXis,of the plow.

Projecting in a slidable manner through each of the flanges 8 and the.plate 9 and adjacent each of the cutters 10 is a pair of push rods 11provided on their outer ends with scraper plates 12 adapted to move overor adjacent the surfaces of this cutte s 10 in order to clear suchsurfaces bf .su ln material as may adhere thereto "during; the

plowing operation as will presently ap' ear.

The normal retracted position of thexpsh rods 11 is maintained byretractile 'springs- 13 secured to each of the rods 11 and-to the platei4 provided with a slotted guide 15 followingthe circular contour oftheplow for the greater portion of the distance the cutters 10 and clearthe same of any' material disposed thereon. v

On the outer end of each of the shafts 6 is a sprocket wheel 19connected by a chain 20 with a sprocket wheel 21 on a shaft 22 journaledon the frame 1. The connection of each of the gears21 with said shaft 22is made by means of a friction clutch '23 for the purpose of allowing adifferential action, if desired, in going around curves or similarplaces. On the shaft 22 is a pair of spaced gears 2-1 and 25, each beingconnected by a chain 24; and 25 respectively, with one of themotivemeans 4 by means of which gear'and chain connections the said plows willbe operated, the forward motion 'ofthe entire device being imparted bythe movement of the plows, the suitable tractive power being due to theweight of the machine on said plows.

Mounted at the rear of each plow member and capable of rotary mention isa drum 26 provided with a plurality of projecting cutter blades 27disposed closely adjacent the members 10. Motion is imparted to themembers 26 by means of chains 28 connecting sprocket gears 29 on theshaft 6 with sprocket gears 30'on the shaft 31 of such members 26.Mounted on the underside of the framel directly in front of each plowmember is a roller. 32 held in contact with the ground surface by meansof expansible springs 33 interposed between the frame 1 and journaledboxes 3% movable in guides 35 in which boxes 3ft are the shafts 36 ofthe said rollers The operation is as follows, namely: With the action ofthe motive means, the plow members are rotated and the plates or cut 1-saidfoul matter will probably adhere to the cutters 10, but just as suchcutters reach a point adjacent the blades 27, the push rods 11 aremoved'outwardly causing the scraper plate 12 to move over the surface ofthe cutter 10 thus clearing the same and the; blades 27, which Will berevolved in a rapid manner with the members 26, thoroughly break up andout such matter into fine parts, removing it as an impediment to theskilful and eiiicient plowing and tilling of the soil.

From the foregoing description it will readily be seen that 1haveproduced such a device as substantially fulfils the objects of theinvention as substantially set forth herein. a

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice, such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is A device of the characterdescribed comprising the combination with a separating frame, of arotary member mounted thereon, a plate fixed to said frame on each sideof said rotary member, a slotted guide member projecting from eachplate, such guide members being concentric With the axis of said rotarymember for a greater portion of their length and being at one pointeccentric with such. axis, projecting flange mem bars on each side ofsaid rotary member,

such flange'members being concentric with the axis of such rotarymember, a plurality of push rods movable through .suclrflange membersand the outer rim of, said 'rotar-y-- member, each push rod having aroller'mo --V able in. one of said guides, springsgscated against saidflange members and'each con nected with one of said push rods, projecting blades on said rotary memberj and scraper plates mounted on saidpush rods and movable over said blades, as desribed. In testimonywhereof I aliix my signature in iirescnce of two witnesses.
